But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.
— Antonin Artaud calculus quote
We can generate immense quantities of data [from dental calculus] that then we can use to begin to reconstruct a detailed picture of the dynamic interplay between diet, infection and immunity, thousands of years ago.

If one looks at the different problems of the integral calculus which arise naturally when one wishes to go deep into the different parts of physics, it is impossible not to be struck by the analogies existing.
— calculus quotation by Henri Poincare

My first degree came years before my second. I had wanted to be a physicist, but I flunked calculus.

Hard to be a physics major at Rice University if you have flunked calculus.

I was more interested in skating and the girls and traveling than I was in calculus.

Gout produces calculus in the kidney.
.. the patient has frequently to entertain the painful speculation as to whether gout or stone be the worst disease. Sometimes the stone, on passing, kills the patient, without waiting for the gout.

Newton, of course, was the inventor of differential calculus so his place in the tale is quite special.

I was always very strong in math, physics and calculus.

Aerodynamics is mathematics for those who haven't learned to do calculus.
In my case, too, for one who hasn't learned to add or multiply, at least the first time.

When I was about thirteen, the library was going to get 'Calculus for the Practical Man.' By this time I knew, from reading the encyclopedia, that calculus was an important and interesting subject, and I ought to learn it.
